Attention to details, very clean and tidy with nice ‘add-ons’ (chargers, game console joysticks, coffee beans, area tips, yoga mats, etc). Full kitchen too, ended up not using as I spent the entire trip museum hopping - which brings the next big plus: walking distance to Reina Sofia, El Prado and Thyssen-Bornemisza museums, Reina Sofia being the closest, I walked to all 3 end enjoyed coffee stops or a beer or two along the way.
The ‘hotel’ is 3 minutes away from El Roble, one of the breakfast places Bob W recommends. I did have dinner there and it was well worth it- recommended!
